CMMVC8478E The mapping cannot be removed because the volume being unmapped has received I/O within the defined volume protection period.
Explanation
Volume protection is enabled, but the volume being unmapped has received I/O recently, within the defined volume protection time period, so the unmapping command fails. Receiving I/O generally indicates that a volume is in use.
User response
- Ensure that this volume is intended to be unmapped. If you selected the wrong volume, repeat the unmapping command with the correct volume.
- To unmap this volume, ensure that no host I/O is sent to the volume, wait the time specified in the vdisk_protection_time field in the lssystem command since the last I/O was received, then retry the unmapping command.
- To disable volume protection and its warnings, disable the vdisk_protection-enabled field in the chsystem command.
